Extra-pair Mating in Tree Swallows
Faithless philandering or cunning cuckoldry?
presented by Dr. Kelly Hallinger
For centuries, birds have been regarded as paragons of monogamy. The past 30 years, however, have cast their unfettered fidelity in a remarkably different light. New molecular genetic techniques have given researchers an unobstructed look at the private lives of birds and resulted in the startling discovery that cuckoldry is common, occurring in more than 75% of all species studied to date. Why promiscuous mating should be so common in the avian world remains an unanswered and contentious question. In this seminar, Kelly will introduce several hypotheses that have been put forward to explain the high incidence of promiscuous mating in birds. Then we get to delve into a detailed examination of one of these hypotheses using data from a long-studied population of Tree Swallows (Tachycineta bicolor) breeding in New York.
